Answer:
archea, protists, heterotrophic
algae
Kingdom fungi and kingdom animalia
Kingdom monera
Because they classified organisms only on the basis of being able to produce their foods or otherwise.
Explanation:
Archaea and bacteria are both prokaryotes, but only archaea can live in hostile environments such as in hot springs. Protists are not monophyletic and so are very diverse, defined as any eukaryote that isn’t a fungus, plant, or animal. Fungi are heterotrophic and cannot produce their own food.
There are different plant groups including algae, bryophytes, ferns, gymnosperms and angiosperms. Out of all these groups, only algae lacks roots or root-like structures. They have a thallus body and water only diffuse in and out of their cells direct from/to the environment.
According to classification of living organisms, there are five kingdoms including monera, protista, fungi, plant, and animal. The only prokaryotic kingdom is the kingdom monera which consists of bacteria and archaea.
Kingdom protista consist of unicellular, animal-like organisms but some members like euglena have the ability to manufacture their foods through photosynthesis. Only fungi and animals are entirely heterotrophic, they depend on external sources for their foods.
Archaea have the ability to exist in extreme environmental conditions such as high temperature, pressure, salinity, etc. They belong to the kingdom monera. <em>They are most likely to be the one to be found in hot springs.</em>
<u>Scientists only include plants and animals in the initial classification levels describing life because they only use the ability to manufacture food or otherwise to group organisms</u>. Those that posses chlorophyll and can therefore manufacture their foods by photosynthesis were grouped as plants while the rest were grouped as animals. It was later that scientists realized that some living organism did not entirely fall into any of the two groups and this led to the emergence of the five kingdom classification.
